DL524

DL524 arrived on time 74.1% of the time, against 76.4% for all ATL → LGA flights, so this departure is 2.3 percentage points worse than the route as a whole. Against Delta Air Lines’ own flights on this route it is 5.2 points worse.

DL524’s scheduled departure has moved during the period FlyerIntel has on file: it typically left around 4:30 PM earlier on, and around 2:30 PM more recently — a 120-minute shift, not the few minutes of day-to-day rounding every published schedule carries. Confirm the current departure time before booking around an older listing.

The aircraft flying DL524 came in 15 or more minutes late on 13% of the departures where its previous flight is known. There are not enough departures in both groups to say how the flight left after a late one and after an on-time one.

Each departure is matched to the flight the same aircraft flew into ATL just before it, using the tail number in the DOT file, 640 of 687 departures in all. A departure is left out when that flight is unknown, was cancelled or diverted, or the aircraft had sat for more than 12 hours. A flight the airline cancelled never left and is not in the count, and one flown by a substitute aircraft is matched to the aircraft that flew it, not to the one first planned.

DL524 pushes back an average of 16.5 minutes late and reaches the gate at LGA an average of 12.4 minutes late. The 4.1 minutes between those two figures are slack the published schedule already carries, which is why a late pushback on this flight does not reliably become a late arrival. It spends 17.3 minutes on the taxiways at ATL, 1.9 minutes longer than a typical ATL departure in the same hour.

On arrival at LGA, DL524 spends 9.0 min taxiing from touchdown to the gate — ground time a connecting passenger sits through before they can even leave the aircraft, on top of however late the flight itself ran. That is about what any arrival at LGA spends on the ground before reaching the gate.

Departure delay is averaged over every pushback and arrival delay over every completed arrival, so the two counts differ by the flights that never reached LGA. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 51,091 departures from ATL scheduled in the clock hour DL524 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at LGA (456,481 flights), not just DL524’s own. More on taxi time.

DL524 is scheduled out of ATL at 2:30 PM, in the 2 PM–3 PM bank. Departures from ATL in that hour arrive on time 78.9% of the time against 78.7% across the airport’s whole day, so the hour DL524 leaves in is an ordinary one for ATL and explains nothing about its record either way.

The two airport figures cover every departure from ATL to every destination, so they describe the slot rather than this journey — the like-for-like comparison against the route is above. Hours are scheduled local, and a number whose schedule moved between banks inside the period has no single hour and is not described here at all. Why the hour matters.

Because the same number has served different journeys, the statistics above describe only the route DL524 currently operates. Blending them would produce an average of two different flights.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. DL524 is placed in the same ordering rather than left out of it; the rows around it are the most punctual departures on the route, not all of them, so this is a comparison and not a rank. Schedules change; confirm the departure still operates before booking around this.
